[0025] Advantageously, the first gear 25 meshes with the second gear 35 , and the third gear 36 meshes with the fourth gear 24 .

[0026] Advantageously, a closing plate 33 is removably provided on one side of the machine body 13, a plurality of bearing seats 29 are provided inside the closing plate 33, a plurality of bearing seats 29 are provided inside the machine body 13, a plurality of bearings 26 are provided on the outer surfaces of the input shaft 23, the transmission shaft 34 and the output shaft 22, and the bearings 26 are provided in the bearing seats 29.

[0027] Advantageously, an inner hole 31 is provided in the bearing seat 29 , and the input shaft 23 , the transmission shaft 34 and the output shaft 22 pass through the inner hole 31 .

[0028] Advantageously, the closing plate 33 and one side of the machine body 13 are provided with a cover plate 28 , and the cover plate 28 is detachably connected to the closing plate 33 and the flange 32 on one side of the machine body 13 .

[0029] Advantageously, a through hole 27 is provided in the cover plate 28 , and the input shaft 23 and the output shaft 22 pass through the through hole 27 .

[0030] Advantageously, a plurality of bearing stop rings 21 are disposed on one side of the cover plate 28 . When the cover plate 28 is installed on one side of the flange 32 , the bearing stop rings 21 abut against one side of the bearing seat 29 , so as to clamp the bearing 26 in the bearing seat 29 .

[0031] Advantageously, the first gear 25 has a smaller number of teeth than the second gear 35 , the third gear 36 has a smaller number of teeth than the second gear 35 , and the third gear 36 has a smaller number of teeth than the fourth gear 24 .

[0032] Advantageously, steps are provided on both sides of the interior of the bearing seat 29 , and the steps are used to place the outer ring of the bearing 26 . The bearing limiting ring 21 abuts against the bearing seat 29 to limit the outer ring of the bearing 26 in the bearing seat 29 .

[0033] Advantageously, stepped shafts are provided at both ends of the input shaft 23 , the transmission shaft 34 and the output shaft 22 , and after the outer rings of the bearings 26 close to the input shaft 23 , the transmission shaft 34 and the output shaft 22 are installed in the bearing seat 29 , the stepped shafts abut against the inner rings of the bearings 26 .

[0034] The transmission function of the reducer can be realized by connecting the input shaft 23 to the input device and the output shaft 22 to the output device; when disassembling, the reducer can be disassembled and separated after the cover plate 28 and the closing plate 33 are removed.

[0035] When disassembling the reducer, the cover plate 28 and the flange 32 are first disassembled and separated. At this time, the bearing limit ring 21 on one side of the cover plate 28 and the bearing seat 29 are released from abutment, and then the closing plate 33 is disassembled from one side of the body 13.

[0036] When removing the closing plate 33 , the closing plate 33 is directly pushed in a direction opposite to the machine body 13 , so that the input shaft 23 , the transmission shaft 34 and the output shaft 22 are separated from the closing plate 33 .

[0037] Then the input shaft 23 , the transmission shaft 34 and the fourth gear 24 can be pulled out from the machine body 13 .

[0038] When there is no need to remove the cover plate 28, the cover plate 28 can be kept installed on one side of the flange 32 and on one side of the body 13. At this time, the closing plate 33 can be directly removed and separated from the body 13, which will cause the bearing 26 arranged in the bearing seat 29 between the cover plate 28 and the closing plate 33 and between the cover plate 28 and the body 13 to remain in the closing plate 33 and the end surface of the body 13; however, it does not affect the disassembly and separation of the closing plate 33 and the body 13. Since the bearing limit ring 21 on the end surface of the cover plate 28 abuts against the end surface of the bearing seat 29 to limit the movement of the bearing 26 in the bearing seat 29, there is no need to install hardware such as clamps when installing the bearing 26 in the bearing seat 29.

[0039] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
